Frequently asked questions
What is the price of CNY17-3 Phototransistor Optocoupler with Base Connection in Egypt?
CNY17-3 Phototransistor Optocoupler with Base Connection currently costs between 8 and 12 EGP across 2 offers in Egypt.
Where can I buy CNY17-3 Phototransistor Optocoupler with Base Connection in Egypt?
CNY17-3 Phototransistor Optocoupler with Base Connection is available from RAM Electronics and Microohm. Compare the offers above to find the best price.
What is the base connection used for?
The exposed base lets you add a resistor between base and emitter to change the gain and switching speed of the phototransistor. Leave it unconnected for normal use.
Can it switch a motor or relay directly?
No. It isolates small logic-level signals. For loads, use its output to drive a transistor or MOSFET, which then switches the relay or motor.
